Don't Sweat It: Eight Common AC Problems and How to Fix It

When the scorching heat of summer arrives, there's nothing more comforting than a well-functioning air conditioning system to keep your home cool and comfortable. However, like any other appliance, air conditioners can encounter problems over time. In this article, we'll explore eight common AC issues and provide simple solutions to help you stay cool when you need it most.

Inadequate Cooling


Problem: Is your AC blowing warm or insufficiently cool air?

Solution: Start by checking the thermostat settings. Ensure it's set to "cool" and the desired temperature. If the problem persists, it could be due to a dirty or clogged air filter. Replace or clean the filter regularly to maintain optimal airflow. If the issue persists, it may be time for professional air conditioning repairs in Perth or any other city in AU.

Poor Airflow

Problem: Is the airflow from your vents weak?

Solution: Inspect the vents and make sure they're not obstructed by furniture or other objects. Clean the vents and ensure they're open. If the problem persists, your AC's blower motor or ductwork may require attention from an HVAC technician.

Strange Noises

Problem: Do you hear unusual sounds coming from your AC, such as banging, hissing, or squealing?

Solution: Unusual noises often indicate a mechanical problem. Turn off the AC immediately and contact a professional technician. Attempting to diagnose or fix the issue yourself could lead to further damage.

Leaking Water

Problem: Is water dripping from your AC unit?

Solution: A leaking AC might be caused by a clogged condensate drain line or a frozen evaporator coil. First, check the condensate drain for blockages and clear them if necessary. If the issue persists, it's time to call a professional for air conditioning repairs.

Foul Odors

Problem: Are unpleasant odours emanating from your AC vents?

Solution: Often, musty smells are the result of mould or mildew growth in the ductwork or on the evaporator coil. Clean or replace the air filter, and consider using an HVAC-specific cleaner to address this issue. If the smell persists, consult a professional.

Constant Cycling

Problem: Is your AC constantly turning on and off?

Solution: This issue, known as short cycling, can strain your AC unit and increase energy consumption. It may be due to a malfunctioning thermostat or a refrigerant leak. Have an HVAC technician diagnose and resolve the problem.

High Energy Bills

Problem: Have you noticed a sudden spike in your energy bills without a corresponding increase in cooling comfort?

Solution: Inefficient AC operation can lead to higher energy costs. Regular maintenance, including cleaning coils and changing filters, can help improve efficiency. If your AC is old and outdated, consider upgrading to a more energy-efficient model.

No Cooling at All

Problem: Is your AC unit not providing any cool air?

Solution: When your AC system fails to cool your home entirely, it can be due to several factors. Check the circuit breaker to ensure the AC unit has power. If the breaker hasn't tripped and the system still isn't working, it's time to call for professional air conditioning repairs.


A well-maintained reverse air conditioning in Perth or any other city is crucial for keeping your home comfortable during the hot summer months. By recognizing these common AC problems and knowing how to address them, you can ensure that your cooling system operates efficiently and reliably. Remember that while some issues can be resolved with simple DIY solutions, others may require the expertise of a professional HVAC technician. Regular maintenance and prompt attention to problems will extend the lifespan of your AC unit and keep you cool throughout the summer season.

So, don't sweat it—stay cool and comfortable by addressing these common AC problems head-on.
